<p>One thing we could discuss, <span class="user-mention" data-user-id="127859">@Taylor Cramer</span>, is the syntax PR. As you know, I'm in favor of landing it (with any syntax, your choice as implementor), under the explicit proviso that the final syntax is not stable (we can cite the internals thread). But maybe we should just wait at this point and discuss it in the lang team meeting. (I moved this to its own topic)</p>

<p>Yup, I'd prefer to get lang-team sign-off before doing this</p>
